It's easy to set up because you point the DNS to it, and it's working in under 15 minutes

Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

Mitigates more bot activity when defending web applications than any other vendor but comes at a price

F5 Silverline Managed Services is expensive. You do get world-class quality of mitigation, but I think it is still pricey. You can find similar services, potentially of slightly lower quality, from other vendors like Cloudflare or Akamai for about half the price. When you compare what you get for the money you spend at Cloudflare or Akamai, you do get less protection but you are not dishing out too much for it. On the other hand, at F5 Silverline Managed Services, you do get better protection but, but you are paying double for it. We have had mixed feedback from our clients about this. Most of them would rather pay less for a bit of a lower-quality defense than overshoot their budget. The most common piece of feedback we receive is that the difference in protection levels is not reflected in the price.

Consistently protect applications with advanced threat detection and active support

We have had a very good experience with Radware Cloud. It has significantly reduced attacks on our applications. All our critical applications are onboarded to Radware, which uses AI to automatically learn behavior patterns and refine security policies. It also provides comprehensive protection against the top ten web application security risks. Importantly, we have not experienced any zero-day attacks because Radware Cloud offers protection against emerging threats. The Emergency Response Team is very active, and I consistently receive excellent responses from them. It's a very comprehensive and user-friendly solution. It's easy to implement and integrate. We also have found it's easy to reach support if we need help. The solution has helped us enhance our cyber security posture. It's good for data protection. We've been able to protect our public-facing infrastructure. We haven't had any incidents or compromises in the entire three years we've used Radware. The Cloud WAF Service blocks unknown threats and attacks effectively. The analytics are very good. The API discovery feature is very helpful, and end-to-end API protection is useful. Everything is encrypted to ensure effective protection. We get Layer 7 protection from it. The API discovery is a very useful feature. It is easy to use. A few months before, I did a demo to learn more. We can see which APIs are being used or not. It helps us discover and remove unused APIs. In our case, we found 20 APIs that were not used by the team. We use the CDN features. It's pretty easy to use the combination of CDN and Cloud WAF. It helps your Radware Cloud connect with the nearest server or the Redware server. We have multiple servers worldwide, so this is useful for us. Integration is very easy. Sometimes, we have 10 to 15 applications hosted on the cloud. It's very easy to add applications. It's not complicated. From the Radware cloud, it's integrated with our SOC. All the logs are received by the SOC.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."

"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."

"The most valuable feature is the web application firewall."

"The solution is stable, and the DNS servers are simple to use."

"There are key things that are used for our enterprise customers, such as Lambda and DNS."

"The solution automatically detects and responds to certain types of traffic based on geolocation."

More Cloudflare pros

"The initial setup is straightforward."

"The most valuable feature is flexibility."

"Its flexibility is the most valuable because it is a managed service. The good part is that you don't need to set it up. It just needs DNS routing, which is the easiest thing. Our client had Akamai for certain websites because they were using CDN features. They had NetScaler on the internal zone, F5 AWAFs on the data centers, and no WAF at all in the cloud. One of the main activities of the project was to move all these policies into a single WAF so that we could control and use that as a choke point. That exercise itself was very easy because it was a managed service and F5 Silverline Web Application Firewall does that for you. That's the best thing about F5 Silverline Web Application Firewall. It is easy to apply policies on-premises. If you have AWAF on-premises and you want to replicate some policies on F5 Silverline Web Application Firewall, other than the policies that it applies by itself, it is easy because you have a team that supports it. F5 Silverline Web Application Firewall works perfectly fine. It pretty much does everything that an Advanced WAF on-premises should do."

"F5 Silverline offers load balancing, flexibility, and reliability."

"Most vendors fulfill the requirements for standard DDoS protection, but F5 Silverline Managed Services has a better understanding of defending web applications like HTTP and can mitigate more bot activity than any other vendor."

"F5 technical support is really good."

"The initial setup is very straightforward."

"The most valuable features are the configuration and configuring the process."

More F5 Silverline Managed Services pros

"With the current visibility dashboard, we can now obtain insight into the nature of attacks, identify attackers, and detect top IP or threat regions."

"The most important aspect of Radware Cloud WAF is that it is over the cloud, offering a comprehensive solution that includes WAF, API protection, bots, and Layer 7 DDoS."

"The isolation feature is the most important one because everything is going directly to Radware first and then it goes into our system. What we get is the filtered version of everything that would otherwise come directly to us."

"Cloud WAF's interface is easy to use and protects us from OWASP Top Ten threats. Our dev team do QA checks on applications before they go live, but Cloud WAF creates an additional security layer on our website."

"The most valuable features of Radware Cloud WAF Service include its automation and learning capabilities for protection, as well as its superior bot mitigation."

"Importantly, we have not experienced any zero-day attacks because Radware Cloud offers protection against emerging threats."

"I like the reliability of the system since it's quite reliable."

"It has significantly reduced attacks on our applications."

More Radware Cloud WAF Service pros

Cons

"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

"The solution could be more user-friendly."

"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."

"The product needs to improve its automation."

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."

More Cloudflare cons

"In terms of the scalability, this part is always so confusing because they are checking for packet count. Also, after an attack, they said that the throughput must be from gigabits but then I check my bandwidth and it is already done in gigabits. So it is a little bit confusing."

"The product could be improved on the global load and the integration with the other solution like Cisco and Dell. As a representor of the operation, we prefer to have one platform which can accommodate all type of integration. We are also looking for more improvements in the security policy configuration."

"The navigation is difficult to use."

"The price of F5 Silverline Managed Services could be better."

"F5 Silverline Managed Services can improve by adding features that Palo Alto has."

"You need to have Linux knowledge in order to use the shell."

"F5 Silverline Web Application Firewall, being a new product in the market or comparatively related to a new product, currently supports less number of PoPs. They should introduce more PoPs. The current number of PoPs that they have is around 10 or 12, which is still relatively less as compared to 2,400 plus PoPs that Akamai offers. The user latency or the number of hops a user needs before reaching the actual web application is less in Akamai because it has its internal fabric to route the traffic. They need to spin up more data to increase its traffic handling capability. They can also include the bot detection capability, though it is a pretty advanced functionality. If they could include DataDome like functionality, that is, bot prediction, then F5 Silverline Web Application Firewall will be top-notch in the market."

"The price is high in comparison to other products."

More F5 Silverline Managed Services cons

"Sometimes, I encounter issues with password reset, particularly in the last two weeks. This indicates some reliability issues or problems within the management interface."

"Our only complaint is the reporting on the DDoS side. We also use Radware for on-premises DDoS protection and their Vision product. I just want to give paint you an example. We face so many Layer 3 and Layer 4 DDoS attacks on Cloud WAF. The reporting on those types of attacks can be improved."

"Radware does not have much online training available to help customers get the most out of this solution."

"We receive many reports from our security team of IPs flagged by our security tools, such as Palo Alto. I cannot add the file containing the IPs to get them blocked; instead, I have to contact Radware support and open a ticket for them to do it. I need to be able to block flagged IPs myself, as it currently takes more time to open a ticket, contact the support team, and wait four to six hours for a response. I want to be able to upload a file with 2,000-3,000 IPs in the console and then apply and save the configuration."

"Radware's bot manager can be improved because it's very complicated to implement for apps. Radware could also add alerts by WhatsApp or Telegram. It only sends notifications via email or SMS."

"Cloud WAF's management portal lacks many indicators, and the interface could be more user-friendly. It should provide more detailed information on events, possible solutions, and what each event means. While it does give you the event and block part, it doesn't give you a solution. Let's say, for example, someone wants to go into an SQL injection and find a possible solution other than the blocking part, there are no details. It would be good to have possible solutions or the ability to create an automated report to send to the developers in the portal."

"The lower-level technical team at Radware could improve their approach to problem-solving as they sometimes are very slow."

"We've had some issues with putting certificates in."

More Radware Cloud WAF Service cons

Pricing and Cost Advice

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."

"The product's pricing is minimal compared to other products."

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

"The tool is a premium product, so it is very expensive."

"The price is reasonable."

"The price of the solution is expensive."

More Cloudflare pricing and cost advice

"The price of F5 Silverline Managed Services could be reduced."

"The product’s pricing is reasonable."

"F5 Silverline Web Application Firewall works based on your bandwidth. They look at the clean bandwidth and do the pricing. 20% of a total pipe would be a clean bandwidth. The list price or a non-negotiated price for F5 Silverline Web Application Firewall would be around $2,200 per application per year for everything that you need. When you get into an enterprise kind of a setup, they negotiate this to the last bit. I would easily take 20% on that, which would be the cost, but it should cover all your Advance WAF features, bot protection, tech campaign, etc. It is built as a package and gives you most of the capability. You don't get the mobile SDK, which is an additional license. Mobile SDK is required only if you're buying or if you have a mobile application, and you are going to instrument F5 or Imperva into your mobile appliance. This anyways would be an additional module. It doesn't come within the WAF, but it is a WAF feature."

"The price of F5 Silverline Managed Services could be better, they are not very flexible. The price of the solution is based on the requirements of the enterprise."

"We are based in El Salvador and don't have a direct license with Radware; we purchase the license through resellers. The pricing is reasonable, as I managed an Akamai product in a previous position, and Cloud WAF is competitively priced."

"Radware Cloud WAF Service falls within a mid-range price bracket compared to other web application firewall solutions."

"When compared to Akamai and F5, Radware's pricing and licensing are highly competitive."

"I am not directly involved in pricing and setup cost discussions, but it seems that Radware offers a more cost-effective solution compared to F5. It is considered a good value for our budget."

"The price is a bulk average."

"I believe the prices are fair."

"We are paying $20,000 annually for six licenses that provide basic WAF functionality."

"For the current market, the price for Radware Cloud WAF Service is exactly where we want it to be."

Reviews from real users

“Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare
comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and
an SSL certificate automatically protects your website. If you have a connection between your
website and your host, the server, Cloudflare, and the host, you don't necessarily need a
certificate.” Spencer M., Owner at Tech Exchange

“What I like best about Cloudflare is that my company can use it to trace and manage
applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare
also sends you a link to check your equipment and deployment and track it through peering,
so it's a valuable tool.” Daniel P., Network Engineer at Ufinet

“The most valuable feature of Cloudflare is the GUI. You are able to control the solution very
well through the interface. There is a lot of functionality that is embedded in the service.” PeerSpot user, Competence Center Manager at a tech services company
